Hi Sascha --Button presses go through the sysmon_pswitch subsystem, and actions are performed based on the "linux,code" property on the node.
linux,code = 116: power button linux,code = 142: sleep button all other values: hotkey button Your sw4 button uses code 256 so it will be treated as a hotkey button. In /etc/rc.conf you'll want to set powerd=YES and then edit the/etc/powerd/scripts/hotkey_button script to handle it. The hotkey events come in by name, so ${1} in that script will be "sw4" and ${2} will be either "pressed" or "released".

It is defined in the dtb just as the leds are and the kernel seems to recognize it: gpiokeys0 at fdt0: sw4 cheers sascha
